Abstract


The use of remote sensing technology to investigate the regional land-use types , quantitative extraction of land use information is currently one of the important research areas . Remote sensing image classification of remote sensing data in the first step of the analysis and application of land resources , how to solve the multi-class image recognition and meet certain accuracy is a key issue in the study of remote sensing images , has a very important significance . More complex feature type Fuzhou Outskirts area a small area of land use classification , for example, spectral characteristics, texture characteristics and topographical features of the integration of remote sensing images to build a multi-source spatial database using C4.5 algorithm training sample data set of spatial database found that the classification rules to classify experimental comparison and analysis with the traditional supervised classification and logical channel classification . The results show that the classification accuracy than traditional supervised classification and logical channel classification method based on C4.5 classification algorithm . C4.5 algorithm to build a decision tree to obtain the classification rules is therefore reasonable , it can quickly and efficiently for a large number of classification rules , it is an effective means to promote knowledge - based remote sensing image classification method is widely used in the land use classification .
